| INTRODUCTION: Introduction | ||
Rocket-powered devices have been in use for more than two thousand years, but it is only in the last three hundred years that rocket experimenters have had a scientific basis for understanding how they work. The science of rocketry began with the publishing of a book, Mathematical Principles of Natural Philosophy, in 1687 by Sir Isaac Newton. His book stated three important scientific principles that govern the motion of objects. This includes rockets, even though the book was written over 300 years ago. These principles are called Newton's Laws of Motion. |
